Abstract

CP asymmetries in B0 decays into CP eigenstates are shown to be very useful in probing effects of new physics. Although there are many possible sources for inconsistencies with the Standard Model predictions, we find that various relations among the asymmetries test different aspects of new physics. We suggest a new way to test the assumption that the direct decays are dominated by a single combination of mixing parameters. We argue that new physics in K-K mixing is unlikely to affect the results. New physics in the mixing of Bd-Bd and Bs-Bs can be probed separately and independently of the unitarity of the CKM matrix. © 1990.
